Yeah if you really dont wanna get caught just act like you did when you first started smoking in your home. I remember what I used to do--sneak around so quiet I couldn't even hear myself (sometimes I took my shirt off cause I thought they'd hear the rustling, haha) and use a page from the phone book to roll a bone cause I was so paranoid about keeping papers in the house. Then I'd go down to the basement with a walkie talkie by the stairs so I could hear if they were coming, I'd smoke it as fast as possible, waste about a half hour of my high being paranoid..... those were the days.
